1. Precision coating system: with the technology of interface polymerization, and the functional layer adopts slot die quantitative coating approach.
2.
Tension correction control system: a segmented high-precision tension correction control system is adopted to prevent product performance loss during processing.
3. Intelligent control system: equipped with an industrial touch screen, the parameters of each section of this system are clear at a glance, the upper computer allows continuously record of the process parameters, so they can be traced.
4.
Modular design: the test line adopts a modular design, which can be selectively used for different processes.
5.
Sampling of the whole process: the diaphragm of each process section can be sampled to facilitate the understanding of the performance changes of the entire process.
